DECKLING MACHINE.

Application filed June 30, 1924. Serial No. 723,283.

provement is to provide mechanism where-v by a photograph mount can be fed in an improved manner through the machine and during one 'passage through the machine have two opposing edges deckled.

Y The machine is composed of duplicate parts and by that it is meant that many parts are used in different locations of the machine, which are duplicates of other parts, set in reverse position from the first mentioned parts.

In general, the machine comprises two distinct units, one `of which is in a sense stationary, while the companion unit is movable in its entirety. Each unit has movable feed supporting parts, as hereinafter more fully described.

Referring to the drawings, Fig. 1 is a 30 plan view of the machine; Fig. 2 is a right end View; Fig. 3 is a transverse section on line 3-3 of Fig. 1 (part of same being in elevation) Fig. 4t is a transverse section on line -l-t of Fig. 1; Fig. 5 is a transverse section on line 5-5 of Fig. 1, taken through the center .cf the feed belts; Fig. G is a transverse section on lineZ- of Fig. 5; Fig. 7 is a transverse section on line 7 7 of Fig. 5; Fig. 8 is a transverse section on line 8-8 `of Fig. 5; Fig. 9 is adiagrammatic view of the transmission mechanism; Fig. 10 is a front elevation on line 10-10 of Fig. 1; Fig. 11 is a sectional view on line 11-11 of Fig. 2.

The base of the machine is indicated by 1 (Figs. 1 and 3).; the motor, illustrated as a prime mover for the various moving parts, is indicated by2; the side frame is indicated by 3 (see Fig. 2). This side frame is-com posed of uprights and spacers, and as indicated in Fig. 2there are two side frames which are duplicates, one of the other, placed side by sidein reverse positions; that is, one end of one side frame is placed ad- .jlCeIlt t0 the OPPOSe end of the companion side frame. Each side frame has an end elevated to a higher plane than the other end, and in Fig. 2 the end of one side frame lying in the lower horizontal plane is shown, while the elevated end of the companion side frame is shown.

The feed mechanism support is indicated at l (Fig. 2) and this support is mounted to slide on the end of the frame 3 lying in the lower horizontal plane. Referring to Fig. 1 the feed mechanism supports carry the two sets of mechanism, one being shown at the right hand side of the ligure and the other at the left side. One unit comprises the fronthalf of the machine having the feed mechanism at the right hand side, supported on the movable feed support, while the deckling devices and other parts are supported directly on the stationary frame, and the rear unit has the deckling devices supported on the elevated part of the stationary frame at the right hand side of the figure. Throughout this specification the front of the machine is that part appearing in Fig. l as nearest the person facing the machine, itbeing understood that the operator stands at that side of the machine and feeds the photograph mounts into the machine from vthe front side thereof, and the mounts are fed out of the machine at the rear part of the Fig. 1.

A drive shaft is indicated by 5, which is coupled to the motor shaft. This shaft is mounted in bearings 6 6 near the front of the machine as indicated in Fig. 3. The transmission devices at the left side of Fig. 9 consist of the shaft 5 carrying a pinion 7 secured to said shaft; pinion 7 engages with the gear 8, which is secured tov the countershaft 9, carrying pinion 10, engaging gear 11 on shaft 13 carrying pinion 12 engaging the gear 14:, which is secured to a stub shaft 15, and this constitutes the transmission for the` vfront feeding mechanism and extends from the drive shaft 5 to the feed rolls, the gear 14 (Fig. 9) being shown in engagement with pinion 16, which is secured to one of the feed rolls, hereinafter more fully described. A similar set of transmission devices for the feed mechanism of the other unit at the rear end of the machineis shown at the right hand of Fig. 9 and is in all respects the same as the transmission just described. It is important in mechanism of this kind that the feed rolls of each set and the feed rolls of the two sets should operate in perfect synchronism, to eliminate any danger of buckling ofl tearing the photograph mounts during the feeding movement. The pinions 16 are shown in mesh with upper pinions 17 and the pinions 18 are shown in.

mesh with upper pinions 19 and these comprise the front set consisting of two pairs of pinions. The pinion 16 is secured to a lower feed roll 21 (see Fig. 5), while the pinion 17 is securedto the upperfeed roll 21. The pinion 19 is secured to anupper feed` roll 24, andthe companion" pinion 18 is securedA toa feed roll 2e. As shownin Fig.`5,rtheref are `two sets of rolls and each set includes two pairs of upper and lower feed rolls.. One set of these feed rolls is part ofthe front unit'ofy the machine, while the other set is in-they rear unit. g The feed 4belts 25 are specially prepared for the work ofv carrying or feeding `the photograph `mounts andto this end the surfaces and `edges are' ground to insure perfect align- Yment of the parts thereof. Each set has an upper and lowerifeed belt and the mount is fed betweenfthe two' belts. It will become apparent that when the photograph mount passes from'the front feed mechanism to the rearfeed mechanism there will always be danger ,ofA impairing the mount unless the feed lrolls of the'rear section and the feed rolls ofthe vfront section are rotated in perfeet synchronism. `Moreover, it isr likewise important' that the upper feed rolls and the lower feedrolls of each vset should operate fin synchronism. VThe rolls 22 and 23l are 'idlers, the'funetion of which is to maintain the feed belt-"inV properalignment and sufliciently'ftaut., f The feed rolls of'the'two sets are the 'same size, besides operating in syn- `chronism,` lto cause beltsto have same linear velocity. l

The mechanism for insuring synchronism between the feed rolls lof one set and the feed rolls of the other setv is shown Vat the lower `end of Fig. 9. Thiscomprises a sprocket chain 2S whicheiitends over two sprocket wheels 29, which are identical in size, one withtlie other. lOne sprocket 29 is at the front part` of the machine on. the shaft 5, secured invany ordinaryway to rotate sivmultaneously with-said shaft, but the other sprocketon areal' driveshaft 30 (see Fig. Ll) is secured 'with elongated hubs to rotate in a forked bearing and this sprocket 29is Vkeyed tothat drive shaftso that the drive Yshaft may slide laterally through said sprocket totake care of the sliding movement of the'rear unit hereinafter more fully set forth. ln this manner the two sets of transmission'mechanism for the feed rolls of the-front yand rear units are interconnected so lthat 'the VfeedV rolls will be positively driven -in'synchroi'iism.y In thisy connection,

y it is important to remember that during the passage" ofy thev 'photograph mount through Vinches to thirty inches.

part. This will-necessarily occur with some mounts of thelarger sizes and the machines are v intended t-o operate on photograph mounts of various widths, say from three In case the feed rolls do not operate in synchronism, there will always be danger by reason of the feeding belt of one unit operating at a different velocityY from the feeding belt of the other unit that Vthe photograph mount will revolve in one direction or another, so that its edge will not be properly presented to bot-h sets of deckling devices, it being understood'that there is a set of deckling devices .foreach vunit ashereinafter more fully `set forth.

y lts shown in Fig. 4, the upper portion of the supporting frame forthe feed `rollsis adjustably mounted, soY that the part4 of the supporting frame to which the upper feed rolls are attached can be raised and lowered Vto enable the operator to have access to the space between the feed rolls for the purpose o-f repairing parts or for any other-purpose. This upper frame is raised and lowered by the wheel 31,- which is secured to a, screw threaded shaft and by lturning this wheel 31 the frame can be raised and lowered in the usual and ordinary way as indicated i-n said figure. There4 is, also shown an end-wise adjustment of the feed supporting mechanism by the wheel 32' (see also Fig. 10). VThe feed supporting frame 4, is'shown with lugs integrally formed thereon and the wheel shaft 58 is mounted sofas-to rotate within said lugs,l but` longitudinal mlovement ,of

said shaftmon saidfsupport 4 isprevented by a shoulder formed( on said shaft and a cap Vsecured to the end of said shaft'. Said shaft is extended through `bracket V59, whichpis bolted Vto the frame 3formed with internal threads, so that by turning the wheel 32 the feed support can be moved relatively to the frame.l In this way, the operator can gain access to the space between the feed `rolls by first Vmoving the feed supportin a horizontal plane so as to remove the feed belt andfeed'rolls from any obstructions that will preventthe upper partl of the frame being elevated as heretofore explained. Thereupon, by turning the wheel 31, theupper part of thefeed support can be elevated usualway The feed roller22-(ll1`igf8') has l'lO its bearing, spring pressed into position, and the shaft to which said bearing is secured has aself aligning ball bearing at its outer end and in this way the upper feed roll 22 of each set is maintained in proper alignmentand maintains the two rollers in proper contact and is capable -of adjustment by the operator.

The table 36 has a gauge 37 for adjusting the position of the mount before it is fed into the machine and 38 is a follow board (Fig. 2) placed on the stock catcher on thev rear of the machine for causing the mounts to stack up in uniform piles.

The belt pulley 39 (Fig. 3) is for a belt which connects the drive shaft 5 with the countershaft 4() (Fig. l), a belt pulley 41 being secured to v'countershaft 40. The bearings for shaft 40 are indicated at 4QF-42. The pulleys 43-443 and belts are to connect countershaft 40v with two deckler shaft-s 44 and a5 (Fig. e);

46 and 46 (Fig. 3) are housings for said "deckler shafts and the support for these housings is indicated at 47. The housing for the upper deckler is adjustably mounted on the support 47 in any usual and ordinary way. The plates 48-48 are arranged toform a conduit for the portion of the mount that extends beyond the feed rolls and belt, and this conduit is madey wide enough' to accommodate the mount of maximum width.

The decklers comprise a series of disks with' serrated edges (Figs. 4 and 7) indicated at 49. The deckler shafts 44 and 45 (Figs.

A 3 and 4) are set at an inclination to the feed cut and the othersv will finish the deckling.

' By reason of arranging the deckler shafts at an inclination to the feed belts, it is desirable to arrange the front set of decklers at a point near the inner part of the machine and the rear set of decklers near the outer part of the machine, otherwise it would `be diticult to locate the deckler shafts, so they would notl interfere with other parts of the machine. j

To eliminate danger of the belts feeding the mount improperly at the point where the decklers attack the edges of the mount and to overcome anytendency to tear the mount back of the edges, it is desirable to reinforce the feed belts near that point and to this end there is shown a pair ofblocks 50` (Fig. 7), each having a flange portion 51. The upper block is spring pressed into engaging position and is shown secured to an anchor rod 52 swiveled at its rear end. Specially hardened and polished plates 53 and 53 are secured to the flangev portions 51 and these plates are maintained in parallelism by the foregoing arrangement of parts,

nism Yof each unit is shown in Fig. 10, wherein 32 indicates the adjusting wheel, 58 is the wheel shaft which is journaled in lugs formed on the support 4. The bracket 59 is secured toy the frame 3 and has internal screw threads and the wheel shaft is formed with blocks or shoulders to prevent any longitudinal movement of the shaft through the lugs. Consequently, when the wheel is rotated, the support 4 will slide upon the frame 3 to enable the operator to gain access to parts that need adjustment or repair.`

In Fig. l1 there is shown a similar adjusting device for the entire rear unit of the' machine. kln Fig. 4 this rear unit is shown slidingly mounted on the base l and inFig. 1lL the adjusting wheel 54 and shaft -55 control the movement of the rear unit. The

internally screw threaded bracket 57 is secured to the base andthe lugs 56 are secured to the frame, so that by turning the wheel the rear unit can be caused to slide upon the base and the drive shaft 30, which is journaled on the frame, will slide through the sprocket, as heretofore explained.

Because the upper deckler and lower deckler are rotated in reverse directions, one belt connecting countershaft 40 with a deckler shaft 45 is shown twisted ig. l).

6l indicates a blower (Fig. 2) which is employed to remove the waste material removed from the edges of the mount by the decklers. This blower is connected to a conduit which extends to the points where each pair of decklers is located,`and isdriven by belts and pulleys secured to shafts 5 and 30, i
